Recently, many datasets for the SISR task have been proposed, including BSDS300 [1]}, DIV2K [2]}, and Flickr2K [3]}. Meanwhile, there are also many test datasets that can be used to effectively test the performance of the models, such as Set5 [4]}, Set14 [5]}, Urban100 [6]}, and Manga109 [7]}. In Table REF , we list a series of commonly used datasets and indicate their detailed attribute.
